Description

Tilting mechanism of electric motor car split front wheel

Technical Field

The utility model belongs to the technical field of the electric motor car, a tilt mechanism of electric motor car split front wheel is related to.

Background

The motorcycle and the battery car are commonly called as the electric vehicle, and the electric vehicle in daily life is mostly a two-wheeled and four-wheeled electric vehicle, and provides the service of riding instead of walk for the user. Then the two-wheeled electric vehicle has no balance and is easy to fall down on a wet road. The common four-wheel electric vehicle has larger volume and high manufacturing cost.

Although there are many three-wheeled electric vehicles on the market, most of them adopt a layout mode of two rear wheels and one front wheel, and although they have balance, for many users, their functions are single; especially, the electric vehicle is easy to turn over relative to the front two-wheel structure when turning, and the requirement of the public cannot be met. In view of such a situation, an electric vehicle with two front wheels and one rear wheel (the wheel track of the two front wheels is less than or equal to 460MM in width, which may also be referred to as split front wheels) appears in the existing market, and the steering, the turning, the heeling and the shock absorption and the bumping of the two front wheels occupy important positions in the electric vehicle with two front wheels and one rear wheel.
